kill switch for the electric ? maplan do the toggle type so do demon tweeks not very expensive but make sure you get a high ampage one .
if its for electric mate the easyest way is on the earth from the battery . no curcit no power

[RobMatthews]

yes the electric:spank

I should rephrase the question actually,im gonna get an electric kill switch(two actually,1 for new drift car in the build and 1 for track car both fd\'s).

Needs to be fia/msa(for comps when im ready)no point doing it twice, question is which wire do i need to interupt to cut off the engine ecu?

actually im being really really lazy cause it only needs to be the ignition wire-correct?or is there a better way?

the idea of a kill switch is that if the car over turns or is in a bad crunch the worst case the fuel lines split or the wire harness is crimped and shorts out creating risk of a fire while your needing to get out or in case you cant get out the marshalls need to pull it for you . if your hurt .
(if it needs to be aprroved for racing then yes they use the ignition curcit too )
is simply just the earth cable from the battery extend the cable to the pull switch thats it .
removing the curcit will stop any risk of sparks or fire. obviously if theres already a fire on impact the marshalls have the exstinguishers but its to stop further sparks from causing and on going problem .
